SUMMARY
OF OPERATING EXPERIENCE l
June 1996 i
i
'Ihe unit began the month in Mode 5, in a planned extension to the refueling outage.
)
On 06/20/96 at 1223 while performing a plant heatup,12A Reactor Coolant Pump failed to start. Trouble j
shooting identified that a relay in the power supply breaker had failed. The power supply breaker was i
repaired and plant heatup resumed on 06/21/96 at 0040.
On 06/25/96 at 0040 a plug located on the Shutdown Cooling Return isolation Valve (1 MOV652) leakoff l
line was found to be leaking. The plant was cooled down and repairs were performed. The valve was returned to service at 0850.
While conducting a plant heatup on 06/26/9611B Reactor Coolant Pump tripped at 0850 due to an actuation of the phase differential relay. Trouble shooting identified an internal short in the stator of the motor. The cause of the failure is still under investigation.
I i
i The unit entered Mode 5, cold shutdown on 06/27/96 at 1358 and remained cooled down through the end of i
the month.
